Another Tank ID

[Rootex]

A neighbor has these tanks and is looking to sell them.
I have a couple questions about if I am reading this tank data correctly?

3aa2015 (steel and 2015 psi?)
6" x 19.5"

Is this the correct PSI, Ive never heard of a tank with that low of a working pressure?

How many CF would these be?

Thanks Y'all

All common BITD for steel cylinders:

1800 psi
2015 psi
2250 psi
2400 psi

These are probably old steel 50s. Captain or a few others are sure to chime in with better details as they outdate my knowledge.

That said they probably make a nice set for shore diving.

50's or close to that.

Probably 50's but steel 50's tend to be 45's without the 10% "+" fill to 2216 psi.

Doubled, they are on the heavy side for 100 cu ft of gas when compared to an X7-100, but they were quite popular in the early-mid 70's as they trim very nicely in the water.

Looks very close to the first set of tanks that I learned to dive with. Mine were twin 50's rated at 1800 PSI with original hdyros from the late 50's.

I had a set of both 1800 psi tanks and a set of 2015 psi tanks. The 1800 psi 50's were a bit taller but both have the same 6.9" diameter and are very close in weight.
